BACKGROUND

The following relates generally to wireless communications, and morespecifically to group delay timing accuracy for positioning.

Wireless communications systems are widely deployed to provide varioustypes of communication content such as voice, video, packet data,messaging, broadcast, and so on. These systems may be capable ofsupporting communication with multiple users by sharing the availablesystem resources (e.g., time, frequency, and power). Examples of suchmultiple-access systems include fourth generation (4G) systems such asLong Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, orLTE-A Pro systems, and fifth generation (5G) systems which may bereferred to as New Radio (NR) systems. These systems may employtechnologies such as code division multiple access (CDMA), time divisionmultiple access (TDMA), frequency division multiple access (FDMA),orthogonal frequency division multiple access (OFDMA), or discreteFourier transform spread orthogonal frequency division multiplexing(DFT-S-OFDM). A wireless multiple-access communications system mayinclude a number of base stations or network access nodes, eachsimultaneously supporting communication for multiple communicationdevices, which may be otherwise known as user equipment (UE).

A wireless communications network may implement techniques to keep trackof the positioning of a UE in the wireless communications network. Insome cases, the UE may transmit or receive positioning reference signalsto or from base stations, which the network may use to determine thepositioning of the UE. Conventional techniques to accurately performtiming measurements for a positioning reference signal are deficient,and positioning techniques in a wireless communications system can beimproved.

DETAILED DESCRIPTION

A user equipment (UE) in a wireless communications system maycommunicate with one or more base stations. A serving base station of aUE may keep track of the location or position of the UE. Variouspositioning techniques may be used to track the UE. In some cases, theUE may be configured to transmit to an uplink positioning referencesignal to the serving base station and one or more neighboring basestations. Additionally or alternatively, the UE may be configured toreceive a downlink positioning reference signal from the serving basestation and one or more neighboring base stations. In some cases, the UEmay estimate its positioning based on the measurements, for examplebased on reference signal time difference measurements. Additionally oralternatively, the UE may transmit measurement reports for the one ormore positioning reference signals to a serving base station.Conventional systems may be deficient in estimating a position of theUE. For example, the UE may experience a variation in group delay whichmay include a part-specific delay, a frequency-specific delay, apath-specific delay, a temperature-specific delay, or any combinationthereof.

According to one or more aspects of the present disclosure, a UE mayreceive a configuration signal. In some aspects, the UE may receive theconfiguration signal from a base station. In some cases, theconfiguration signal may indicate a configuration for a positioningreference signal. In some cases, the configuration signal may beassociated with a downlink positioning reference signal transmitted by aserving or neighboring cell. The UE may determine one or more propertiesassociated with the positioning reference signal based on theconfiguration signal. In one example, the one or more properties mayinclude identifying one or more measurement gaps, one or more guardperiods associated with a scheduled transmission of an uplinkpositioning reference signal, or a combination thereof. Additionally oralternatively, using the one or more properties, the UE may determinewhether the positioning reference signal is intended for performingpositioning measurements, performing communications, or any combinationthereof.

In some cases, the UE may determine one or more timings associated withthe positioning reference signal. Additionally, the UE may determine anaccuracy level associated with one or more timing measurements based onthe one or more properties associated with the positioning referencesignal. For example, the UE may determine an accuracy expected on one ormore timing measurements based on one or more transmission ormeasurement properties. In some examples, the UE may determine anaccuracy level associated with a transmission timing for the positioningreference signal, an accuracy level associated with a reception timingfor the positioning reference signal, an accuracy level associated witha time difference between a reception of the positioning referencesignal and a transmission of a second positioning reference signal, orany combination thereof. The UE may then transmit a measurement reportassociated with the positioning reference signal to the base station. Insome examples, the measurement report may be related to the accuracylevel associated with the one or more timing measurements.

Aspects of the disclosure are initially described in the context of awireless communications system. Aspects of the disclosure are furtherillustrated by and described with reference to apparatus diagrams,system diagrams, and flowcharts that relate to group delay timingaccuracy for positioning in NR.

FIG. 1 illustrates an example of a wireless communications system 100that supports group delay timing accuracy for positioning in NR inaccordance with aspects of the present disclosure. The wirelesscommunications system 100 includes base stations 105, UEs 115, and acore network 130. In some examples, the wireless communications system100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A)network, an LTE-A Pro network, or a New Radio (NR) network. In somecases, wireless communications system 100 may support enhanced broadbandcommunications, ultra-reliable (e.g., mission critical) communications,low latency communications, or communications with low-cost andlow-complexity devices.

Base stations 105 may wirelessly communicate with UEs 115 via one ormore base station antennas. Base stations 105 described herein mayinclude or may be referred to by those skilled in the art as a basetransceiver station, a radio base station, an access point, a radiotransceiver, a NodeB, an eNodeB (eNB), a next-generation NodeB orgiga-NodeB (either of which may be referred to as a gNB), a Home NodeB,a Home eNodeB, or some other suitable terminology. Wirelesscommunications system 100 may include base stations 105 of differenttypes (e.g., macro or small cell base stations). The UEs 115 describedherein may be able to communicate with various types of base stations105 and network equipment including macro eNBs, small cell eNBs, gNBs,relay base stations, and the like.

Each base station 105 may be associated with a particular geographiccoverage area 110 in which communications with various UEs 115 issupported. Each base station 105 may provide communication coverage fora respective geographic coverage area 110 via communication links 125,and communication links 125 between a base station 105 and a UE 115 mayutilize one or more carriers. Communication links 125 shown in wirelesscommunications system 100 may include uplink transmissions from a UE 115to a base station 105, or downlink transmissions from a base station 105to a UE 115. Downlink transmissions may also be called forward linktransmissions while uplink transmissions may also be called reverse linktransmissions.

The geographic coverage area 110 for a base station 105 may be dividedinto sectors making up a portion of the geographic coverage area 110,and each sector may be associated with a cell. For example, each basestation 105 may provide communication coverage for a macro cell, a smallcell, a hot spot, or other types of cells, or various combinationsthereof. In some examples, a base station 105 may be movable andtherefore provide communication coverage for a moving geographiccoverage area 110. In some examples, different geographic coverage areas110 associated with different technologies may overlap, and overlappinggeographic coverage areas 110 associated with different technologies maybe supported by the same base station 105 or by different base stations105. The wireless communications system 100 may include, for example, aheterogeneous LTE/LTE-A/LTE-A Pro or NR network in which different typesof base stations 105 provide coverage for various geographic coverageareas 110.

The term “cell” refers to a logical communication entity used forcommunication with a base station 105 (e.g., over a carrier), and may beassociated with an identifier for distinguishing neighboring cells(e.g., a physical cell identifier (PCID), a virtual cell identifier(VCID)) operating via the same or a different carrier. In some examples,a carrier may support multiple cells, and different cells may beconfigured according to different protocol types (e.g., machine-typecommunication (MTC), narrowband Internet-of-Things (NB-IoT), enhancedmobile broadband (eMBB), or others) that may provide access fordifferent types of devices. In some cases, the term “cell” may refer toa portion of a geographic coverage area 110 (e.g., a sector) over whichthe logical entity operates.

UEs 115 may be dispersed throughout the wireless communications system100, and each UE 115 may be stationary or mobile. A UE 115 may also bereferred to as a mobile device, a wireless device, a remote device, ahandheld device, or a subscriber device, or some other suitableterminology, where the “device” may also be referred to as a unit, astation, a terminal, or a client. A UE 115 may also be a personalelectronic device such as a cellular phone, a personal digital assistant(PDA), a tablet computer, a laptop computer, or a personal computer. Insome examples, a UE 115 may also refer to a wireless local loop (WLL)station, an Internet of Things (IoT) device, an Internet of Everything(IoE) device, or an MTC device, or the like, which may be implemented invarious articles such as appliances, vehicles (e.g. automobile, bicycle,etc.), meters, wearables (e.g., watches, glasses, clothing, shoes,jewelry, head mounted displays, etc.), home devices (e.g., locks,lights, displays, etc.), video/audio devices (e.g. televisions,speakers, etc.), health diagnostic devices, therapeutic devices or thelike.

Some UEs 115, such as MTC or IoT devices, may be low cost or lowcomplexity devices, and may provide for automated communication betweenmachines (e.g., via Machine-to-Machine (M2M) communication). M2Mcommunication or MTC may refer to data communication technologies thatallow devices to communicate with one another or a base station 105without human intervention. In some examples, M2M communication or MTCmay include communications from devices that integrate sensors or metersto measure or capture information and relay that information to acentral server or application program that can make use of theinformation or present the information to humans interacting with theprogram or application. Some UEs 115 may be designed to collectinformation or enable automated behavior of machines. Examples ofapplications for MTC devices include smart metering, inventorymonitoring, water level monitoring, equipment monitoring, healthcaremonitoring, wildlife monitoring, weather and geological eventmonitoring, fleet management and tracking, remote security sensing,physical access control, and transaction-based business charging.

Some UEs 115 may be configured to employ operating modes that reducepower consumption, such as half-duplex communications (e.g., a mode thatsupports one-way communication via transmission or reception, but nottransmission and reception simultaneously). In some examples half-duplexcommunications may be performed at a reduced peak rate. Other powerconservation techniques for UEs 115 include entering a power saving“deep sleep” mode when not engaging in active communications, oroperating over a limited bandwidth (e.g., according to narrowbandcommunications). In some cases, UEs 115 may be designed to supportcritical functions (e.g., mission critical functions), and a wirelesscommunications system 100 may be configured to provide ultra-reliablecommunications for these functions.

In some cases, a UE 115 may also be able to communicate directly withother UEs 115 (e.g., using a peer-to-peer (P2P) or device-to-device(D2D) protocol). One or more of a group of UEs 115 utilizing D2Dcommunications may be within the geographic coverage area 110 of a basestation 105. Other UEs 115 in such a group may be outside the geographiccoverage area 110 of a base station 105, or be otherwise unable toreceive transmissions from a base station 105. In some cases, groups ofUEs 115 communicating via D2D communications may utilize a one-to-many(1:M) system in which each UE 115 transmits to every other UE 115 in thegroup. In some cases, a base station 105 facilitates the scheduling ofresources for D2D communications. In other cases, D2D communications arecarried out between UEs 115 without the involvement of a base station105.

Base stations 105 may communicate with the core network 130 and with oneanother. For example, base stations 105 may interface with the corenetwork 130 through backhaul links 132 (e.g., via an S1, N2, N3, orother interface). Base stations 105 may communicate with one anotherover backhaul links 134 (e.g., via an X2, Xn, or other interface) eitherdirectly (e.g., directly between base stations 105) or indirectly (e.g.,via core network 130).

The core network 130 may provide user authentication, accessauthorization, tracking, Internet Protocol (IP) connectivity, and otheraccess, routing, or mobility functions. The core network 130 may be anevolved packet core (EPC), which may include at least one mobilitymanagement entity (MME), at least one serving gateway (S-GW), and atleast one Packet Data Network (PDN) gateway (P-GW). The MME may managenon-access stratum (e.g., control plane) functions such as mobility,authentication, and bearer management for UEs 115 served by basestations 105 associated with the EPC. User IP packets may be transferredthrough the S-GW, which itself may be connected to the P-GW. The P-GWmay provide IP address allocation as well as other functions. The P-GWmay be connected to the network operators IP services. The operators IPservices may include access to the Internet, Intranet(s), an IPMultimedia Subsystem (IMS), or a Packet-Switched (PS) Streaming Service.

At least some of the network devices, such as a base station 105, mayinclude subcomponents such as an access network entity, which may be anexample of an access node controller (ANC). Each access network entitymay communicate with UEs 115 through a number of other access networktransmission entities, which may be referred to as a radio head, a smartradio head, or a transmission/reception point (TRP). In someconfigurations, various functions of each access network entity or basestation 105 may be distributed across various network devices (e.g.,radio heads and access network controllers) or consolidated into asingle network device (e.g., a base station 105).

Wireless communications system 100 may operate using one or morefrequency bands, typically in the range of 300 megahertz (MHz) to 300gigahertz (GHz). Generally, the region from 300 MHz to 3 GHz is known asthe ultra-high frequency (UHF) region or decimeter band, since thewavelengths range from approximately one decimeter to one meter inlength. UHF waves may be blocked or redirected by buildings andenvironmental features. However, the waves may penetrate structuressufficiently for a macro cell to provide service to UEs 115 locatedindoors. Transmission of UHF waves may be associated with smallerantennas and shorter range (e.g., less than 100 km) compared totransmission using the smaller frequencies and longer waves of the highfrequency (HF) or very high frequency (VHF) portion of the spectrumbelow 300 MHz.

Wireless communications system 100 may also operate in a super highfrequency (SHF) region using frequency bands from 3 GHz to 30 GHz, alsoknown as the centimeter band. The SHF region includes bands such as the5 GHz industrial, scientific, and medical (ISM) bands, which may be usedopportunistically by devices that may be capable of toleratinginterference from other users.

Wireless communications system 100 may also operate in an extremely highfrequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz),also known as the millimeter band. In some examples, wirelesscommunications system 100 may support millimeter wave (mmW)communications between UEs 115 and base stations 105, and EHF antennasof the respective devices may be even smaller and more closely spacedthan UHF antennas. In some cases, this may facilitate use of antennaarrays within a UE 115. However, the propagation of EHF transmissionsmay be subject to even greater atmospheric attenuation and shorter rangethan SHF or UHF transmissions. Techniques disclosed herein may beemployed across transmissions that use one or more different frequencyregions, and designated use of bands across these frequency regions maydiffer by country or regulating body.

In some cases, wireless communications system 100 may utilize bothlicensed and unlicensed radio frequency spectrum bands. For example,wireless communications system 100 may employ License Assisted Access(LAA), LTE-Unlicensed (LTE-U) radio access technology, or NR technologyin an unlicensed band such as the 5 GHz ISM band. When operating inunlicensed radio frequency spectrum bands, wireless devices such as basestations 105 and UEs 115 may employ listen-before-talk (LBT) proceduresto ensure a frequency channel is clear before transmitting data. In somecases, operations in unlicensed bands may be based on a carrieraggregation configuration in conjunction with component carriersoperating in a licensed band (e.g., LAA). Operations in unlicensedspectrum may include downlink transmissions, uplink transmissions,peer-to-peer transmissions, or any combination of these. Duplexing inunlicensed spectrum may be based on frequency division duplexing (FDD),time division duplexing (TDD), or a combination of both.

In some examples, base station 105 or UE 115 may be equipped withmultiple antennas, which may be used to employ techniques such astransmit diversity, receive diversity, multiple-input multiple-output(MIMO) communications, or beamforming. For example, wirelesscommunications system 100 may use a transmission scheme between atransmitting device (e.g., a base station 105) and a receiving device(e.g., a UE 115), where the transmitting device is equipped withmultiple antennas and the receiving device is equipped with one or moreantennas. MIMO communications may employ multipath signal propagation toincrease the spectral efficiency by transmitting or receiving multiplesignals via different spatial layers, which may be referred to asspatial multiplexing. The multiple signals may, for example, betransmitted by the transmitting device via different antennas ordifferent combinations of antennas. Likewise, the multiple signals maybe received by the receiving device via different antennas or differentcombinations of antennas. Each of the multiple signals may be referredto as a separate spatial stream, and may carry bits associated with thesame data stream (e.g., the same codeword) or different data streams.Different spatial layers may be associated with different antenna portsused for channel measurement and reporting. MIMO techniques includesingle-user MIMO (SU-MIMO) where multiple spatial layers are transmittedto the same receiving device, and multiple-user MIMO (MU-MIMO) wheremultiple spatial layers are transmitted to multiple devices.

Beamforming, which may also be referred to as spatial filtering,directional transmission, or directional reception, is a signalprocessing technique that may be used at a transmitting device or areceiving device (e.g., a base station 105 or a UE 115) to shape orsteer an antenna beam (e.g., a transmit beam or receive beam) along aspatial path between the transmitting device and the receiving device.Beamforming may be achieved by combining the signals communicated viaantenna elements of an antenna array such that signals propagating atparticular orientations with respect to an antenna array experienceconstructive interference while others experience destructiveinterference. The adjustment of signals communicated via the antennaelements may include a transmitting device or a receiving deviceapplying certain amplitude and phase offsets to signals carried via eachof the antenna elements associated with the device. The adjustmentsassociated with each of the antenna elements may be defined by abeamforming weight set associated with a particular orientation (e.g.,with respect to the antenna array of the transmitting device orreceiving device, or with respect to some other orientation).

In one example, a base station 105 may use multiple antennas or antennaarrays to conduct beamforming operations for directional communicationswith a UE 115. For instance, some signals (e.g. synchronization signals,reference signals, beam selection signals, or other control signals) maybe transmitted by a base station 105 multiple times in differentdirections, which may include a signal being transmitted according todifferent beamforming weight sets associated with different directionsof transmission. Transmissions in different beam directions may be usedto identify (e.g., by the base station 105 or a receiving device, suchas a UE 115) a beam direction for subsequent transmission and/orreception by the base station 105.

Some signals, such as data signals associated with a particularreceiving device, may be transmitted by a base station 105 in a singlebeam direction (e.g., a direction associated with the receiving device,such as a UE 115). In some examples, the beam direction associated withtransmissions along a single beam direction may be determined based atleast in in part on a signal that was transmitted in different beamdirections. For example, a UE 115 may receive one or more of the signalstransmitted by the base station 105 in different directions, and the UE115 may report to the base station 105 an indication of the signal itreceived with a highest signal quality, or an otherwise acceptablesignal quality. Although these techniques are described with referenceto signals transmitted in one or more directions by a base station 105,a UE 115 may employ similar techniques for transmitting signals multipletimes in different directions (e.g., for identifying a beam directionfor subsequent transmission or reception by the UE 115), or transmittinga signal in a single direction (e.g., for transmitting data to areceiving device).

A receiving device (e.g., a UE 115, which may be an example of a mmWreceiving device) may try multiple receive beams when receiving varioussignals from the base station 105, such as synchronization signals,reference signals, beam selection signals, or other control signals. Forexample, a receiving device may try multiple receive directions byreceiving via different antenna subarrays, by processing receivedsignals according to different antenna subarrays, by receiving accordingto different receive beamforming weight sets applied to signals receivedat a plurality of antenna elements of an antenna array, or by processingreceived signals according to different receive beamforming weight setsapplied to signals received at a plurality of antenna elements of anantenna array, any of which may be referred to as “listening” accordingto different receive beams or receive directions. In some examples areceiving device may use a single receive beam to receive along a singlebeam direction (e.g., when receiving a data signal). The single receivebeam may be aligned in a beam direction determined based on listeningaccording to different receive beam directions (e.g., a beam directiondetermined to have a highest signal strength, highest signal-to-noiseratio, or otherwise acceptable signal quality based on listeningaccording to multiple beam directions).

In some cases, the antennas of a base station 105 or UE 115 may belocated within one or more antenna arrays, which may support MIMOoperations, or transmit or receive beamforming. For example, one or morebase station antennas or antenna arrays may be co-located at an antennaassembly, such as an antenna tower. In some cases, antennas or antennaarrays associated with a base station 105 may be located in diversegeographic locations. A base station 105 may have an antenna array witha number of rows and columns of antenna ports that the base station 105may use to support beamforming of communications with a UE 115.Likewise, a UE 115 may have one or more antenna arrays that may supportvarious MIMO or beamforming operations.

In some cases, wireless communications system 100 may be a packet-basednetwork that operate according to a layered protocol stack. In the userplane, communications at the bearer or Packet Data Convergence Protocol(PDCP) layer may be IP-based. A Radio Link Control (RLC) layer mayperform packet segmentation and reassembly to communicate over logicalchannels. A Medium Access Control (MAC) layer may perform priorityhandling and multiplexing of logical channels into transport channels.The MAC layer may also use hybrid automatic repeat request (HARQ) toprovide retransmission at the MAC layer to improve link efficiency. Inthe control plane, the Radio Resource Control (RRC) protocol layer mayprovide establishment, configuration, and maintenance of an RRCconnection between a UE 115 and a base station 105 or core network 130supporting radio bearers for user plane data. At the Physical layer,transport channels may be mapped to physical channels.

In some cases, UEs 115 and base stations 105 may support retransmissionsof data to increase the likelihood that data is received successfully.HARQ feedback is one technique of increasing the likelihood that data isreceived correctly over a communication link 125. HARQ may include acombination of error detection (e.g., using a cyclic redundancy check(CRC)), forward error correction (FEC), and retransmission (e.g.,automatic repeat request (ARQ)). HARQ may improve throughput at the MAClayer in poor radio conditions (e.g., signal-to-noise conditions). Insome cases, a wireless device may support same-slot HARQ feedback, wherethe device may provide HARQ feedback in a specific slot for datareceived in a previous symbol in the slot. In other cases, the devicemay provide HARQ feedback in a subsequent slot, or according to someother time interval.

Time intervals in LTE or NR may be expressed in multiples of a basictime unit, which may, for example, refer to a sampling period ofT_(s)=1/30,720,000 seconds. Time intervals of a communications resourcemay be organized according to radio frames each having a duration of 10milliseconds (ms), where the frame period may be expressed asT_(f)=307,200 T_(s). The radio frames may be identified by a systemframe number (SFN) ranging from 0 to 1023. Each frame may include 10subframes numbered from 0 to 9, and each subframe may have a duration of1 ms. A subframe may be further divided into 2 slots each having aduration of 0.5 ms, and each slot may contain 6 or 7 modulation symbolperiods (e.g., depending on the length of the cyclic prefix prepended toeach symbol period). Excluding the cyclic prefix, each symbol period maycontain 2048 sampling periods. In some cases, a subframe may be thesmallest scheduling unit of the wireless communications system 100, andmay be referred to as a transmission time interval (TTI). In othercases, a smallest scheduling unit of the wireless communications system100 may be shorter than a subframe or may be dynamically selected (e.g.,in bursts of shortened TTIs (sTTIs) or in selected component carriersusing sTTIs).

In some wireless communications systems, a slot may further be dividedinto multiple mini-slots containing one or more symbols. In someinstances, a symbol of a mini-slot or a mini-slot may be the smallestunit of scheduling. Each symbol may vary in duration depending on thesubcarrier spacing or frequency band of operation, for example. Further,some wireless communications systems may implement slot aggregation inwhich multiple slots or mini-slots are aggregated together and used forcommunication between a UE 115 and a base station 105.

The term “carrier” refers to a set of radio frequency spectrum resourceshaving a defined physical layer structure for supporting communicationsover a communication link 125. For example, a carrier of a communicationlink 125 may include a portion of a radio frequency spectrum band thatis operated according to physical layer channels for a given radioaccess technology. Each physical layer channel may carry user data,control information, or other signaling. A carrier may be associatedwith a pre-defined frequency channel (e.g., an evolved universal mobiletelecommunication system terrestrial radio access (E-UTRA) absoluteradio frequency channel number (EARFCN)), and may be positionedaccording to a channel raster for discovery by UEs 115. Carriers may bedownlink or uplink (e.g., in an FDD mode), or be configured to carrydownlink and uplink communications (e.g., in a TDD mode). In someexamples, signal waveforms transmitted over a carrier may be made up ofmultiple sub-carriers (e.g., using multi-carrier modulation (MCM)techniques such as orthogonal frequency division multiplexing (OFDM) ordiscrete Fourier transform spread OFDM (DFT-S-OFDM)).

The organizational structure of the carriers may be different fordifferent radio access technologies (e.g., LTE, LTE-A, LTE-A Pro, NR).For example, communications over a carrier may be organized according toTTIs or slots, each of which may include user data as well as controlinformation or signaling to support decoding the user data. A carriermay also include dedicated acquisition signaling (e.g., synchronizationsignals or system information, etc.) and control signaling thatcoordinates operation for the carrier. In some examples (e.g., in acarrier aggregation configuration), a carrier may also have acquisitionsignaling or control signaling that coordinates operations for othercarriers.

Physical channels may be multiplexed on a carrier according to varioustechniques. A physical control channel and a physical data channel maybe multiplexed on a downlink carrier, for example, using time divisionmultiplexing (TDM) techniques, frequency division multiplexing (FDM)techniques, or hybrid TDM-FDM techniques. In some examples, controlinformation transmitted in a physical control channel may be distributedbetween different control regions in a cascaded manner (e.g., between acommon control region or common search space and one or more UE-specificcontrol regions or UE-specific search spaces).

A carrier may be associated with a particular bandwidth of the radiofrequency spectrum, and in some examples the carrier bandwidth may bereferred to as a “system bandwidth” of the carrier or the wirelesscommunications system 100. For example, the carrier bandwidth may be oneof a number of predetermined bandwidths for carriers of a particularradio access technology (e.g., 1.4, 3, 5, 10, 15, 20, 40, or 80 MHz). Insome examples, each served UE 115 may be configured for operating overportions or all of the carrier bandwidth. In other examples, some UEs115 may be configured for operation using a narrowband protocol typethat is associated with a predefined portion or range (e.g., set ofsubcarriers or RBs) within a carrier (e.g., “in-band” deployment of anarrowband protocol type).

In a system employing MCM techniques, a resource element may consist ofone symbol period (e.g., a duration of one modulation symbol) and onesubcarrier, where the symbol period and subcarrier spacing are inverselyrelated. The number of bits carried by each resource element may dependon the modulation scheme (e.g., the order of the modulation scheme).Thus, the more resource elements that a UE 115 receives and the higherthe order of the modulation scheme, the higher the data rate may be forthe UE 115. In MIMO systems, a wireless communications resource mayrefer to any combination of a radio frequency spectrum resource, a timeresource, and a spatial resource (e.g., spatial layers), and the use ofmultiple spatial layers may further increase the data rate forcommunications with a UE 115.

Devices of the wireless communications system 100 (e.g., base stations105 or UEs 115) may have a hardware configuration that supportscommunications over a particular carrier bandwidth, or may beconfigurable to support communications over one of a set of carrierbandwidths. In some examples, the wireless communications system 100 mayinclude base stations 105 and/or UEs 115 that support simultaneouscommunications via carriers associated with more than one differentcarrier bandwidth.

Wireless communications system 100 may support communication with a UE115 on multiple cells or carriers, a feature which may be referred to ascarrier aggregation or multi-carrier operation. A UE 115 may beconfigured with multiple downlink component carriers and one or moreuplink component carriers according to a carrier aggregationconfiguration. Carrier aggregation may be used with both FDD and TDDcomponent carriers.

In some cases, wireless communications system 100 may utilize enhancedcomponent carriers (eCCs). An eCC may be characterized by one or morefeatures including wider carrier or frequency channel bandwidth, shortersymbol duration, shorter TTI duration, or modified control channelconfiguration. In some cases, an eCC may be associated with a carrieraggregation configuration or a dual connectivity configuration (e.g.,when multiple serving cells have a suboptimal or non-ideal backhaullink). An eCC may also be configured for use in unlicensed spectrum orshared spectrum (e.g., where more than one operator is allowed to usethe spectrum). An eCC characterized by wide carrier bandwidth mayinclude one or more segments that may be utilized by UEs 115 that arenot capable of monitoring the whole carrier bandwidth or are otherwiseconfigured to use a limited carrier bandwidth (e.g., to conserve power).

In some cases, an eCC may utilize a different symbol duration than othercomponent carriers, which may include use of a reduced symbol durationas compared with symbol durations of the other component carriers. Ashorter symbol duration may be associated with increased spacing betweenadjacent subcarriers. A device, such as a UE 115 or base station 105,utilizing eCCs may transmit wideband signals (e.g., according tofrequency channel or carrier bandwidths of 20, 40, 60, 80 MHz, etc.) atreduced symbol durations (e.g., 16.67 microseconds). A TTI in eCC mayconsist of one or multiple symbol periods. In some cases, the TTIduration (that is, the number of symbol periods in a TTI) may bevariable.

Wireless communications system 100 may be an NR system that may utilizeany combination of licensed, shared, and unlicensed spectrum bands,among others. The flexibility of eCC symbol duration and subcarrierspacing may allow for the use of eCC across multiple spectrums. In someexamples, NR shared spectrum may increase spectrum utilization andspectral efficiency, specifically through dynamic vertical (e.g., acrossthe frequency domain) and horizontal (e.g., across the time domain)sharing of resources.

A UE in a wireless communications system may communicate with one ormore base stations. Each base station may provide a cell which extendswithin a coverage area of the base station. The UE may move within thecoverage area, and the cell may provide wireless communications (e.g.,NR communications, or others) to the UE. A serving base station of a UEmay keep track of the location or positioning of the UE. Variouspositioning techniques may be used to track the UE. In some cases, theUE may be configured to transmit an uplink positioning reference signalto the serving base station and one or more neighboring base stations.In some cases, the UE may be configured to receive a downlinkpositioning reference signal from the serving base station and one ormore neighboring base stations. For an uplink positioning referencesignal, the base station and the neighboring base stations may exchangeinformation associated with the receipt of the uplink positioningreference signal, such as reference signal time difference measurementsmade by the UE. The network (e.g., including the one or more basestations) may then determine the location of the UE based on the one ormore uplink positioning reference signal transmissions. For downlinkpositioning reference signal transmissions, the UE may receive apositioning reference signal from each of one or more base stations. Insome cases, UE may estimate its positioning based on the measurements,for example, based on reference signal time difference measurements.Additionally or alternatively, the UE may transmit measurement reportsfor the one or more positioning reference signals to a serving basestation.

In some conventional systems, a UE may experience delay in processingthe positioning reference signal. For example, the delay may be based onradio frequency front-end processing (such as processing at one or moreantennas) at the UE. In some cases, the UE may calibrate the radiofrequency front-end group delays such that a measurement report reflectsthe radio frequency front-end group delay. Thus, in conventionalsystems, the UE may not be able to accurately perform timingmeasurements due to a variation in group delay. As one example, the UEmay detect a part-specific delay while performing measurementsassociated with the positioning reference signal. Additionally oralternatively, the UE may be pre-configured (such as via a manufacturer)to experience a part-specific delay while performing measurementsassociated with the positioning reference signal. Other sources ofvariation in group delay may be frequency-specific, path-specific,temperature-specific, or any combination thereof. Thus, improvedaccuracy in performing one or more timing measurements may be desired.

According to one or more aspects of the present disclosure, a UE 115 mayinclude a UE communications manager (not shown) as depicted in theexamples of FIGS. 5, 6, and 7 and a base station 105 may include a basestation communications manager (not shown) as depicted in the examplesof FIGS. 9, 10, and 11. The UE 115 may receive a configuration signal.In some cases, the configuration signal may indicate a configuration fora positioning reference signal. That is, the UE 115 may receive aconfiguration related to a downlink positioning reference signaltransmitted by a serving or neighboring cell. The UE 115 may determineone or more properties associated with the positioning reference signalbased on the configuration signal. Additionally, the UE 115 maydetermine one or more properties associated with an uplink positioningreference signal based on the configuration signal. In one example, theone or more properties may include identifying one or more measurementgaps and one or more guard periods associated with a scheduledtransmission of the uplink positioning reference signal. In some cases,the UE 115 may identify one or more timings and may determine anaccuracy level associated with one or more timing measurements based onidentifying the one or more properties associated with the uplinkpositioning reference signal. For example, the UE 115 may determine anaccuracy expected on one or more timing measurements based on one ormore transmission or measurement properties. In some examples, the oneor more timing measurements may include a group delay calibration, atransmission timing measurement, a reception timing measurement, or anycombination thereof. The UE 115 may then transmit a measurement reportassociated with the positioning reference signal to the base station105. In some examples, the measurement report may be related to theaccuracy level associated with the one or more timing measurements. Insome cases, the UE 115 may determine the accuracy level associated withthe one or more timing measurements based on receiving an indicationfrom the base station 105 (such as in the configuration signal or theconfiguration message). In some examples, the accuracy level may be apositioning accuracy associated with the position measurementuncertainty at the UE 115.

FIG. 2 illustrates an example of a wireless communications system 200that supports group delay timing accuracy for positioning in NR inaccordance with aspects of the present disclosure. In some examples, thewireless communications system 200 may implement aspects of wirelesscommunications system 100. The wireless communications system 200 mayinclude one or more base stations 105 and one or more UEs 115, forexample including base station 105-a, base station 105-b, base station105-c, and UE 115-a. The base stations 105 described in FIG. 2 may beexamples of the base stations 105 described with reference to FIG. 1. Insome examples, base station 105-a, base station 105-b, and base station105-c may be referred to as a network device and/or a next generationNodeB (gNB). UE 115-a may be an example of a UE 115 described withreference to FIG. 1. Base station 105-a may be an example of a servingbase station 105 for UE 115-a, while base station 105-b and base station105-c may be examples of neighboring base stations 105.

The wireless communications system 200 may illustrate operations of andcommunications between the base stations 105 and the UEs 115 thatsupport determining accuracy for timing measurements for positioning inNR. Each base station 105 may provide a cell, where a base station 105can provide service for a UE 115 within the coverage area of the cell.UE 115-a may move within the coverage area, and the cell may providewireless communications to UE 115-a. In some cases, UE 115-a may beallocated a bandwidth part to communicate with a serving base station.Some examples of the wireless communications system 200 may support animproved timing accuracy determination procedures for positioning in NR.In some cases, the UE 115 may support identifying properties of apositioning reference signal, and utilizing the properties in order toreduce delay in timing measurements.

In some instances, the wireless communications system 200 may supportbeamformed communications, where a base station 105 and the UE 115-a maycommunicate using directional, beamformed transmissions. For this andother reasons (e.g., mobility management, etc.), the base station 105(such as serving base station 105-a) may keep track of the location ofUE 115-a and other UEs 115. Base stations 105 (such as one or more ofbase station 105-a, base station 105-b, and base station 105-c) and UE115-a may implement a variety of techniques to support locationmanagement of wireless devices within the wireless communicationssystem.

In some examples, the wireless network, including base station 105-a,may keep track of the geographic location or positioning of UE 115-a.Various positioning techniques may be used to track UE 115-a. Sometechniques for determining the positioning of UE 115-a may includenetwork-assisted Global Navigation Satellite System (GNSS) techniques(e.g., Global Positioning System (GPS)), barometric pressure sensing,wireless local area network (WLAN) signaling, Bluetooth signaling, andTerrestrial Beacon System techniques, among others. The implementationof some techniques may be based on the radio access technology (RAT)used for wireless communications between UE 115-a and the base stations105. For example, techniques which use downlink positioning, trackingvia an enhanced cell ID, and uplink positioning may be based on the RAT.Additionally or alternatively, base station 105-a and other, neighboringbase station 105-b and base station 105-c may transmit a signal ofinterest, such as a positioning reference signal. The UE 115-a mayreceive and perform measurements on the signal of interest from the basestations 105 (e.g., base station 105-a, base station 105-b, and basestation 105-c). These measurements may include observed time differenceof arrival measurements, such as a reference signal time differenceestimate.

In some cases, the UE 115-a may report the measurements or estimatesmade from the positioning reference signals (such as uplink positioningreference signal 220 and downlink positioning reference signal 215) to abase station (such as base station 105-a). In some cases, the basestation 105-a may use the measurements to detect, or estimate, thepositioning of the UE 115-a. Additionally or alternatively, the UE 115-amay estimate its positioning based on the measurements and transmit anestimation of positioning to base station 105-a. In some examples, theestimates or measurements may be sent to a location management function(LMF), and the LMF may estimate the location or positioning of UE 115-a.

In conventional wireless communications systems, the UE 115-a mayexperience delay in processing the positioning reference signal. Forexample, the delay may be based on radio frequency front-end processing(such as processing at one or more antennas) at the UE 115-a. In suchcases, the UE 115-a is configured to calibrate the radio frequencyfront-end group delays such that a measurement report (such as a reportindicating the measurements or estimates made from the positioningreference signals) reflects the radio frequency front-end group delayexperienced at the UE 115-a. In such cases, upon receiving themeasurement report, the base station 105-a may be configured to subtractthe indicated radio frequency front-end group delay in order tocalculate a distance from the UE 115-a. However, conventional wirelesscommunications systems do not account for other sources of variation ingroup delay. As one example, the UE 115-a may detect a part-specific(such as hardware present in analog and digital paths) delay whileperforming measurements associated with the positioning referencesignal. In some examples, multiple instances of reference designs ofhardware may be tested to measure part-by-part variation. Additionallyor alternatively, the UE 115-a may experience a frequency-specific delayin measurements associated with the positioning reference signal. Insome cases, the accuracy of measurements associated with the positioningreference signal may be based on a portion of the frequency band wherethe positioning reference signal was received. In one example, adifference is measurement between a positioning reference signaltransmitted at a lower band edge and a positioning reference signaltransmitted at an upper band edge of a 5 GHz frequency band may be 500ps. In such cases, the UE 115-a may be configured to calibrate perchannel in order to avoid the discrepancies in timing measurements.

In some instances, the UE 115-a may experience a path-specific delaywhile performing measurements associated with the positioning referencesignal. For example, the delay may be based on a selected antenna orpanel, a transmission power, a transmission processing operation, areceive power, a receive processing operation, or any combinationthereof. In some cases, the UE 115-a may experience atemperature-specific delay while performing measurements associated withthe positioning reference signal. In such examples, the UE 115-a maymaintain a calibration table for temperature. Additionally oralternatively, the UE 115-a may experience other sources of error (suchas calibration errors, measurement precision, etc.) while performingmeasurements associated with the positioning reference signal.

In conventional wireless communications systems, some parts or blocks inthe transmitter or receiver of the UE 115-a may have relatively largegroup delay variations. As one example, a surface acoustic wave filterfor sub-6 frequency range may have a large group delay variations. Table1 demonstrates an example group delay variation of a surface acousticwave filter.

According to one or more aspects of the present disclosure, the UE 115-aand the base station 105-a may implement techniques to support enhancedpositioning schemes and techniques. Specifically, one or more aspects ofthe present disclosure provide for the UE 115-a and the base station105-b to determine an accuracy associated with at least one of a groupdelay calibration, transmission timing, reception timing, or anycombination thereof. For example, the base station 105-a may transmit aconfiguration signal 210 indicating a configuration for a signal ofinterest (e.g., the positioning reference signal) to the UE 115-a, andthe UE 115-a may determine an accuracy level associated with one or moretiming measurements based on the one or more properties associated withthe positioning reference signal as indicated in the configuration. Insome cases, the UE 115-a may receive the configuration signal 210 in ahigher layer signaling (such as an RRC signaling).

In some cases, UE 115-a may be configured to transmit to an uplinkpositioning reference signal 220 to the serving base station 105 and oneor more neighboring base stations 105. In some cases, the UE 115-a maybe configured to receive a downlink positioning reference signal 215from the serving base station 105 and one or more neighboring basestations 105. Upon receipt of an uplink PRS positioning referencesignal, base station 105-a, base station 105-b, and base station 105-cmay exchange, for example via backhaul links, and information associatedwith the receipt of the uplink positioning reference signal 220, such asreference signal time difference measurements made by UE 115-a. Thenetwork (e.g., including the base stations) may then determine thelocation of UE 115-a based on the one or more uplink positioningreference signal 220. For downlink positioning reference signaltechniques, the UE 115-a may receive a downlink positioning referencesignal 215 from each of one or more base stations 105 (e.g., basestation 105-a, base station 105-b, base station 105-c, or anycombination thereof). In some cases, UE may estimate its positioningbased on the measurements, for example based on reference signal timedifference measurements. Additionally or alternatively, the UE 115-a maytransmit measurement reports for the one or more positioning referencesignals (such as uplink positioning reference signal 220 and/or downlinkpositioning reference signal 215) to a serving base station 105-a.

As previously discussed, a positioning technique may be UE-based orUE-assisted. In UE-based positioning, the UE 115-a may perform thepositioning estimation without feeding back reference signal timedifference measurements to the network (e.g., via a base station 105).In some cases, the UE 115-a may perform a UE-based positioning estimatebased on received downlink positioning reference signal 215. In anotherexample, the UE 115-a may receive positioning reference signalmeasurement reports from multiple base stations 105 in the networkcorresponding to one or more transmitted uplink positioning referencesignal 220. The UE 115 may determine a position estimate from thereceived positioning reference signal measurement reports. InUE-assisted positioning, the UE 115-a may provide the reference signaltime difference measurements, and the network may perform thepositioning estimation using the reference signal time differencemeasurements. the UE 115-a may be configured for a UE-based mode, aUE-assisted mode, or a mode which incorporates aspects of both. The usedpositioning mode may be based on a connection initializationconfiguration, downlink control information, a media access control(MAC) control element (CE), etc.

The wireless communications system 200 may support a positioningreference signal resource 225. For example, base station 105-a mayconfigure the positioning reference signal resource 225 for UE 115-a.The positioning reference signal resource 225 may span a bandwidth orfrequency domain allocation. The base station 105-a may configure thepositioning reference signal resource 225 using the configuration signal210. In some cases, the configuration may include one or moreconfigurations for the positioning reference signal resource 225. Forexample, the base station 105-a may indicate to the UE 115-a, afrequency domain allocation for the positioning reference signalresource 225 and use the positioning reference signal resource 225 toreceive a downlink positioning reference signal 215 or transmit anuplink positioning reference signal 220.

As discussed herein, a downlink positioning reference signal 215 may betransmitted by a serving or neighboring cell can be configured to betransmitted in the bandwidth of the positioning reference signalresource 225. Additionally or alternatively, an uplink positioningreference signal may be transmitted by UE 115-a toward a serving orneighboring cell. The UE 115-a may similarly transmit the positioningreference signal in a positioning reference signal bandwidth for theuplink positioning reference signal 220. The UE 115-a may determine anaccuracy expected on one or more timing measurements based on one ormore transmission or measurement properties. In some examples, the oneor more timing measurements may include a group delay calibration, atransmission timing measurement, a reception timing measurement, or anycombination thereof.

According to one or more aspects of the present disclosure, the UE 115-amay identify one or more measurement gaps associated with a scheduledtransmission of the positioning reference signal (such as uplinkpositioning reference signal 220 and/or downlink positioning referencesignal 215). Additionally or alternatively, the UE 115-a may identifyand one or more guard periods associated with a scheduled transmissionof the positioning reference signal. In some cases, the one or moremeasurement gaps and/or the one or more guard periods may be scheduledbefore the positioning reference signal, after the positioning referencesignal, or any combination thereof. That is, the UE 115-a may identify ameasurement gap before or after the downlink positioning referencesignal 215 or the uplink positioning reference signal 220. Themeasurement gap may span a number of symbols (e.g., OFDM symbols) duringwhich the UE 115-a is not expected to transmit or receive any othersignal (e.g., in up to all carriers). In some cases, a base station(such as base station 105-a) may signal the measurement gap to the UE115-a. In some cases, the measurement gap may be indicated to be 0symbols long, or the measurement gap may not be indicated at all.

Upon identifying the one or more measurement gaps and/or one or moreguard periods, the UE 115-a may determine an accuracy for timingmeasurements associated with a transmission of a positioning referencesignal. In some cases, the positioning reference signal may include asounding reference signal. Specifically, the UE 115-a may bypass atleast one portion of a transmit chain associated with the scheduledtransmission of an uplink positioning reference signal or a receivechain associated with a scheduled reception of a downlink positioningreference signal (such as uplink positioning reference signal 220 and/ordownlink positioning reference signal 215). For example, in order toimprove the accuracy for timing measurements, the UE 115-a may bypassone or more blocks or parts of the transmit chain during transmission ofa positioning reference signal. The one or more blocks or parts of thetransmit chain may include a surface acoustic wave filter. In such acase, the UE 115-a may be configured to switch off the surface acousticwave filter during the measurement gap and/or guard period and performthe timing measurements. After completion of the timing measurements,the UE 115-a may switch on the surface acoustic wave filter. That is,the UE 115-a may stop its regular transmissions while performing ameasurement associated with the positioning reference signal, and maythen switch on the surface acoustic wave filter to continue with itsregular transmissions. As described herein with reference to Table 1, agroup delay variation for a surface acoustic wave filter is high. Thus,by bypassing the use of the surface acoustic wave filter, the UE 115-amay increase the accuracy associated with one or more timingmeasurements for the positioning reference signal (such as uplinkpositioning reference signal 220 and/or downlink positioning referencesignal 215).

In some cases, the UE 115-a may receive the configuration signal 210 andmay identify whether a positioning reference signal (such as uplinkpositioning reference signal 220 and/or downlink positioning referencesignal 215) is intended for performing positioning measurements,performing communications, or any combination thereof. In some cases,the UE 115-a may perform this identification based on the receivedconfiguration signal 210. If the UE 115-a determines that thepositioning reference signal (such as a sounding reference signal) isintended for positioning purposes, then the UE 115-a may bypass at leastone portion of a transmit chain associated with a scheduled transmissionof the positioning reference signal. For example, the UE 115-a maybypass one or more blocks of the transmit chain associated with apositioning reference signal. Additionally or alternatively, the UE115-a may transmit the positioning reference signal in a manner whichincreases the group delay or timing accuracy. In some cases, bypassingone or more blocks of the transmit chain associated with a positioningreference signal may not be favorable for communication purposes. Insuch cases, the UE 115-a may identify that the positioning referencesignal (such as uplink positioning reference signal 220) is intended forperforming both positioning measurements and communications. The UE115-a may then determine a second accuracy level associated with the oneor more timing measurements based on the identifying. The accuracy levelassociated with positioning reference signal intended for performingpositioning measurements may be greater than the second accuracy levelassociated with positioning reference signal intended for performingboth positioning measurements and communications. That is, if the UE115-a determines that a positioning reference signal (such as a soundingreference signal) is intended to be used for both positioning andcommunication, then the UE 115-a may not be able to perform changes inthe transmit chain structure, and the group delay/timing accuracy may belower.

According to one or more aspects of the present disclosure, the UE 115-amay receive the configuration signal 210 and may determine whether apositioning reference signal is simultaneously transmitted with achannel. In some cases, the UE 115-a may perform the determination basedon receiving the configuration signal 210. In some instances, thechannel may be in the same component carrier as the positioningreference signal or a different component carrier as the positioningreference signal. In some examples, the UE 115-a may determine theaccuracy level associated with the one or more timing measurements arebased on the determination. The UE 115-a may determine that a change inthe transmission of the positioning reference signal may affect otherphysical channel transmission on the same component carrier or differentcomponent carrier.

According to some implementations, the UE 115-a may determine whether atransmission power associated with a positioning reference signalsatisfies a threshold. In some cases, the UE 115-a may receive theconfiguration signal 210. For example, the UE 115-a may receive theconfiguration signal 210 from the base station 105-a, and may performthe determination based on the configuration signal 210. In some cases,the accuracy level associated with one or more timing measurements maybe based on the identifying. If the UE 115-a determines that thetransmission power associated with the positioning reference signalsatisfies the threshold, then the UE 115-a may bypass at least oneportion of a transmit chain associated with a scheduled transmission ofthe positioning reference signal (such as uplink positioning referencesignal 220). In one example, if the transmission power associated with apositioning reference signal (such as a sounding reference signal) isgreater than a threshold, the UE 115-a may determine that bypassing aportion of the transmit chain may hamper the emissions requirement. Insuch cases, the UE 115-a may determine a second accuracy levelassociated with the timing measurement for the positioning referencesignal. Alternatively, if the UE 115-a determines that the transmissionpower associated with a positioning reference signal is less than thethreshold, then the UE 115-a may choose to bypass a portion (such as asurface acoustic wave filter) of the transmit chain in order to achievehigher accuracy for timing measurements. In some cases, the thresholdmay be or may be based on a UE capability 205. In some cases, the UE115-a may report the UE capability 205 to a base station (such as basestation 105-a). The UE capability 205 may be associated with a frequencyband, a combination of frequency bands, or both.

According to one or more aspects of the present disclosure, the UE 115-amay identify a duration of the positioning reference signal during aperiod of time. In some cases, the UE 115-a may identify the durationbased on the configuration signal 210. The UE 115-a may then determinewhether the duration of the positioning reference signal satisfies athreshold. For example, the UE 115-a may determine whether the durationof a positioning reference signal burst during a specific period of timeis configured as short bursts. Upon determining that the duration of thepositioning reference signal satisfies the threshold, the UE 115-a maybypass least one portion of a transmit chain associated with a scheduledtransmission of the positioning reference signal. That is, if the UE115-a determines that a positioning reference signal (such as a soundingreference signal) is configured as short bursts of resources over aspecific period of time (e.g., 1 ms), then the UE 115-a may bypass thesurface acoustic wave filter and achieve higher accuracy. In some cases,the duration of the positioning reference signal may include a number ofsymbols.

In some instances, the UE 115-a may identify a bandwidth associated withthe positioning reference signal. For example, the UE 115-a may identifythe bandwidth based on a configuration signal 210. Although it isdiscussed that the UE 115-a receives the configuration signal from abase station, it may be understood that the UE 115-a may receive theconfiguration signal from a different device. In some cases, the UE115-a may receive the configuration signal from a device using adifferent communication technology than the UE 115-a. For example, theUE 115-a may be operating using NR technology, and may receive theconfiguration signal from a device operating using a Wi-Fi technology ora Bluetooth technology. In some cases, the UE 115-a may receive theconfiguration signal using peer-to-peer connection. For example, the UE115-a may receive the configuration signal from a nearby device (such asa second UE 115 or an IoT device) using peer-to-peer connection. In someexamples, the UE 115-a may determine that the bandwidth associated withthe positioning reference signal satisfies a positioning referencesignal bandwidth threshold. In some cases, an accuracy level associatedwith one or more timing measurements may be non-proportional to thebandwidth associated with the positioning reference signal. For example,the accuracy level may not be proportionally inverse to a bandwidth fora sounding reference signal, as a high bandwidth may be associated withdifferent transmission-reception calibration. As a result, differentpositioning reference signal bandwidth thresholds may be associated withdifferent accuracies.

According to one or more aspects of the present disclosure, the UE 115-amay identify a location of a sub-band associated with a scheduledtransmission of the positioning reference signal. For instance, the UE115-a may identify whether the positioning reference signal istransmitted in an edge of a sub-band, or in a center of a sub-band. Insome cases, an accuracy associated with the sub-band located at a centerof a frequency band may be greater than an accuracy associated with thesub-band located at an edge of the frequency. In some examples, thelocation of the sub-band may be based on a UE capability reported to thebase station 105-a. Additionally or alternatively, the UE 115-a maydetermine that the accuracy level associated with the one or more timingmeasurements is different for a first frequency range and a secondfrequency range.

In some cases, the UE 115-a may transmit a measurement report 230associated with the positioning reference signal. The measurement report230 may be related to the accuracy level associated with the one or moretiming measurements. The base station may receive the measurement report230, and may determine the position of the UE 115-a based on themeasurement report 230.

FIG. 3A illustrates an example of timing estimation 300 that supportsgroup delay timing accuracy for positioning in NR in accordance withaspects of the present disclosure. FIG. 3B illustrates an example oftiming estimation 350 that supports group delay timing accuracy forpositioning in NR in accordance with aspects of the present disclosure.In some examples, timing estimation 300 and timing estimation 350 mayimplement aspects of wireless communications system 100.

As depicted in the example of FIGS. 3A and 3B, a base station maydetermine a position of a UE position based on a time of arrivalestimation. As described in FIG. 3A, a base station (such as basestation 105) may transmit a downlink reference signal at time T₁. The UEmay receive the downlink reference signal at time T₂. In some cases, theUE may measure a time of arrival for the downlink reference signal attime T₂. In some cases, the UE may transmit an uplink reference signalat T₃. Additionally, the UE may transmit a UE measurement reportT_(Rx→Tx). For example, the UE measurement report T_(Rx→Tx) may indicatea time difference between receiving a downlink reference signal andtransmitting an uplink reference signal (i.e., T₃−T₂). The base stationmay receive the uplink reference signal at time T₄. The base station maythen measure the time of arrival for the uplink reference signal at timeT₄ and determine a gNB measurement report T_(Tx→Rx). Specifically, thebase station may determine a gNB measurement report T_(Tx→Rx)=T₄−T₁ (ora time difference between transmitting a downlink reference signal andreceiving an uplink reference signal). The base station may thencalculate a distance from the UE based on the gNB measurement report andthe UE measurement report. In one example, the base station maycalculate the distance d as:

$d = {{\frac{1}{2c}\left( {T_{{Tx}\rightarrow{Rx}} - T_{{Rx}\rightarrow{Tx}}} \right)} = {{\frac{1}{2c}\left( {T_{2} - T_{1}} \right)} - {\frac{1}{2c}\left( {T_{4} - T_{3}} \right)}}}$

With respect to FIG. 3B, a base station (such as base station 105) maytransmit a downlink reference signal at time T₁. The downlink referencesignal may be transmitted from the radio frequency front end of the basestation at time T₁₁. The UE may receive the downlink reference signal attime T₂₁. That is, an antenna at the UE downlink reference signal attime T₂₁, and the radio frequency front end of the UE may completereception of the downlink reference signal at time T₂. In some cases,the UE may measure a time of arrival for the downlink reference signalat time T₂. In some cases, the UE may transmit an uplink referencesignal at T₃, and the uplink reference signal may be transmitted throughthe radio frequency front end of the UE at time T₃₁. In some cases, theUE may transmit a UE measurement report T_(Rx→Tx) indicating a timedifference between receiving a downlink reference signal andtransmitting an uplink reference signal (i.e., T₃−T₂). The base stationmay receive the uplink reference signal at time T₄₁ and the radiofrequency front end of the base station may receive the uplink referencesignal at time T₄. The base station may measure the time of arrival forthe uplink reference signal at time T₄ and determine a gNB measurementreport T_(Tx→Rx) based on a time difference between transmitting adownlink reference signal and receiving an uplink reference signal. Insome cases, the gNB measurement report T_(Tx→Rx) may be based on arelative downlink/uplink frame timing and specification location for theuplink reference signal. In some cases, the UE may experience groupdelay due to the presence of the radio frequency front end. In somecases, the UE may calibrate the radio frequency front end group delaysand compensate for the radio frequency front end. In such cases, the UEmeasurement report may indicate the group delay associated with theradio frequency front end. The base station may then calculate adistance from the UE by subtracting the calibrated radio frequency frontend group delays.

FIG. 4 illustrates an example of a process flow 400 that supports groupdelay timing accuracy for positioning in NR in accordance with aspectsof the present disclosure. In some examples, the process flow 400 mayimplement aspects of wireless communications system 100. The processflow 400 may include base station 105-d and UE 115-c, which may beexamples of the corresponding devices described with reference to FIGS.1 through 3. UE 115-c and base station 105-d may support accuracy leveldetermination for various timing measurements in NR.

In the following description of the process flow 400, the operationsbetween UE 115-c and base station 105-d may be transmitted in adifferent order than the exemplary order shown. The operations performedby UE 115-c or base station 105-d may be performed in different ordersor at different times than the exemplary order shown. Some operationsmay also be left out of the process flow 400, or other operations may beadded to the process flow 400. Further, UE 115-c and base station 105-dare not meant to be representative, as the described features may beassociated with any number of devices.

At 405, base station 105-d may transmit a configuration signalindicating a configuration for a positioning reference signal. The UE115-c may receive the configuration signal via higher-layer signaling(such as RRC signaling). In some cases, the configuration signal mayindicate one or more properties associated with the positioningreference signal.

At 410, the UE 115-c may determine one or more properties associatedwith the positioning reference signal based on the configuration signal.As depicted in the example of FIG. 4, the UE 115-c may optionallydetermine multiple properties associated with the positioning referencesignal in order to determine an accuracy level associated with timingmeasurements.

At 415, the UE 115-c may optionally identify one or more measurementgaps associated with at least one scheduled transmission of apositioning reference signal (such as an uplink positioning referencesignal). Additionally or alternatively, the UE 115-c may identify one ormore guard periods associated with at least one scheduled transmissionof the positioning reference signal. In some cases, the UE 115-c maydetermine that the one or more measurement gaps and the one or moreguard periods are scheduled before the positioning reference signal,after the positioning reference signal, or any combination thereof.

At 420, the UE 115-c may determine an intended use of the referencesignal (such as the positioning reference signal). In some examples, theUE 115-c may receive an indication (such as included in theconfiguration signal) for the intended use of the positioning referencesignal. For example, the base station 105-d may indicate the intendeduse of the positioning reference signal in the configuration signal. Insome examples, the base station 105-d may use one or more bits toindicate the intended use of the positioning reference signal.

In some cases, the UE 115-c may identify, based on the configurationsignal, whether the positioning reference signal is intended forperforming positioning measurements, performing communications, or anycombination thereof. Additionally or alternatively, the UE 115-c maydetermine an intended use of a reference signal based on determiningwhether the reference signal is a positioning reference signal. In somecases, the UE 115-c may determine that a reference signal is intendedfor performing measurements if the reference signal is a positioningreference signal. Alternatively, the UE 115-c may identify that thepositioning reference signal is intended for performing the positioningmeasurements and the communications. In some examples, the positioningreference signal may include a sounding reference signal.

At 425, the UE 115-c may determine whether a transmission powerassociated with the positioning reference signal satisfies a threshold.In some cases, the identifying is based on the configuration signal. Insome examples, the UE 115-c may identify that the transmission powerassociated with the positioning reference signal satisfies thethreshold. Alternatively, the UE 115-c may determine that thetransmission power associated with the positioning reference signal doesnot satisfy the threshold. In some cases, the UE 115-c may report a UEcapability to the base station 105-d. In some cases, the UE capabilitymay be associated with a frequency band, a combination of frequencybands, or both. In such examples, the threshold may be based on the UEcapability.

At 430, the UE 115-c may determine an accuracy level associated with oneor more timing measurements based on the one or more propertiesassociated with the positioning reference signal. In some cases, the UE115-c may identify (such as receive, obtain, or otherwise identify) theone or more timing measurements prior to determining the accuracy level.For example, the UE 115-c may determine an accuracy level associatedwith a transmission timing for the positioning reference signal, anaccuracy level associated with a reception timing for the positioningreference signal, an accuracy level associated with a time differencebetween a reception of the positioning reference signal and atransmission of a second positioning reference signal, or anycombination thereof.

At 435, the UE 115-c may optionally bypass at least one portion of atransmit chain associated with the scheduled transmission of thereference signal (such as the positioning reference signal). In somecases, bypassing the at least one portion of the transmit chain is basedon identifying the one or more measurement gaps and the one or moreguard periods. Additionally or alternatively, the UE 115-c may bypass atleast one portion of a transmit chain associated with the scheduledtransmission of the positioning reference signal based on identifyingthat the positioning reference signal is intended for performing thepositioning measurements. Additionally or alternatively, the UE 115-cmay bypass at least one portion of a transmit chain associated with ascheduled transmission of the positioning reference signal based onidentifying that the transmission power associated with the positioningreference signal satisfies the threshold. In some cases, the UE 115-cmay bypass one or more components that are part of the transmit chain.For example, the one or more components may include one or more filters(such as surface acoustic wave filters), one or more power amplifiers,or any combination thereof.

At 440, the UE 115-c may transmit a measurement report associated withthe positioning reference signal. In some cases, the measurement reportmay be related to the accuracy level associated with the one or moretiming measurements.

FIG. 5 shows a block diagram 500 of a device 505 that supports groupdelay timing accuracy for positioning in NR in accordance with aspectsof the present disclosure. The device 505 may be an example of aspectsof a UE 115 as described herein. The device 505 may include a receiver510, a UE communications manager 515, and a transmitter 520. The device505 may also include a processor. In one example, the device 505 may bean example of an embodiment of system 800 as depicted in the example ofFIG. 8. Additionally or alternatively, the device 505 may be an exampleof a portion of the system 800. Each of these components may be incommunication with one another (e.g., via one or more buses). In someexamples, the receiver 510 and the transmitter 520 may be implementedseparately or in integrated transceiver hardware/software.

The receiver 510 may include an Rx processor 525, a MIMO detector 530, afilter 535, and a power amplifier 540. The receiver 510 may receiveinformation such as packets, user data, or control informationassociated with various information channels (e.g., control channels,data channels, and information related to group delay timing accuracyfor positioning in NR, etc.). Information may be passed on to othercomponents of the device 505. The receiver 510 may be an example ofaspects of the transceiver 820 described with reference to FIG. 8. Thereceiver 510 may utilize a single antenna or a set of antennas. Each ofthese sub-components of the receiver 510 may be in communication withone another (e.g., via one or more buses). The receiver 510, or itssub-components, may be physically located at various positions,including being distributed such that portions of functions areimplemented at different physical locations by one or more physicalcomponents. In some examples, the receiver 510, or its sub-components,may be a separate and distinct component in accordance with variousaspects of the present disclosure.

The receiver 510 may receive the downlink signals from a base station(such as base station 105) and may provide the received signals to oneor more demodulators (not shown). In some cases, the demodulator may beincluded in the Rx processor 525. A demodulator may condition (e.g.,filter, amplify, downconvert, and digitize) a respective received signalto obtain input samples, and process the input samples (e.g., for OFDM,etc.) to obtain received symbols. A MIMO detector 530 may obtainreceived symbols from all the Rx processor 525, perform MIMO detectionon the received symbols if applicable, and provide detected symbols. TheRx processor 525 may further process (e.g., demodulate, deinterleave,and decode) the detected symbols, providing decoded data for the UE to adata output, and providing decoded control information to the UEcommunications manager 515.

The UE communications manager 515 may receive a configuration signalindicating a configuration for a positioning reference signal. Forexample, the UE communications manager 515 may receive the configurationsignal through the receiver 510. The UE communications manager 515 maydetermine one or more properties associated with the positioningreference signal based on the configuration signal, determine orotherwise identify one or more timings associated with the positioningreference signal. In one example, the UE communications manager 515 maybypass the filter 535 and/or power amplifier 540 associated with ascheduled reception of a positioning reference signal. Additionally oralternatively, the UE communications manager 515 may bypass the filter555 and/or power amplifier 560 associated with a scheduled transmissionof a positioning reference signal. In some cases, the UE communicationsmanager 515 may decide to bypass the filter based on the one or moreproperties. The UE communications manager 515 may then determine anaccuracy level associated with one or more timing measurements based ondetermining the one or more timings associated with the positioningreference signal and the one or more properties associated with thepositioning reference signal. The UE communications manager 515 inconjunction with the transmitter 520 may transmit a measurement reportassociated with the positioning reference signal, where the measurementreport is related to the accuracy level associated with the one or moretiming measurements. In one example, the accuracy level or an accuracyapproximation for the one or more timing measurements may be included inthe measurement report. The UE communications manager 515 may be anexample of aspects of the UE communications manager 810 describedherein.

The UE communications manager 515, or its sub-components, may beimplemented in hardware, code (e.g., software or firmware) executed by aprocessor, or any combination thereof. If implemented in code executedby a processor, the functions of the UE communications manager 515, orits sub-components may be executed by a general-purpose processor, adigital signal processor (DSP), an application-specific integratedcircuit (ASIC), a field programmable gate array (FPGA) or otherprogrammable logic device, discrete gate or transistor logic, discretehardware components, or any combination thereof designed to perform thefunctions described in the present disclosure. It may be understood thatthe UE communications manager 515, or its sub-components, may beimplemented without a modem baseband or a processor.
